FRIDAY, Oct. 5, 2018 (HealthDay News) — Digital cognitive behavioral therapy (dCBT) is effective in improving functional health, psychological well-being, and sleep-related quality of life in people reporting insomnia, according to a study published online Sept. 25 in JAMA Psychiatry<\/i>.<\/p>\n
Colin A. Espie, Ph.D., from the University of Oxford in the United Kingdom, and colleagues assessed the effect of dCBT for insomnia on functional health, psychological well-being, and sleep-related quality of life among 1,711 participants (77 percent female) with self-reported symptoms of insomnia. Participants were randomized to dCBT for insomnia or sleep hygiene education (SHE). Functional health was measured on a scale of 10 to 50, with higher scores indicating better health; psychological well-being was measured on a scale of 14 to 70, with higher scores indicating greater well-being; and sleep-related quality of life was measured on a scale of 1 to 100, with higher scores indicating greater impairment.<\/p>\n
The researchers found that use of dCBT was associated with a small improvement in functional health compared with SHE (adjusted difference at week four: 0.9, 95 percent confidence interval [CI], 0.4 to 1.4; at week eight: 1.76, 95 percent CI, 1.24 to 2.28; at week 24: 1.76, 95 percent CI, 1.22 to 2.3; all P < 0.01). There was also a small improvement in psychological well-being (adjusted difference at week four: 1.04, 95 percent CI, 0.28 to 1.8; at week eight: 2.68, 95 percent CI, 1.89 to 3.47; at week 24: 2.95, 95 percent CI, 2.13 to 3.76; all P < 0.01). There was a large improvement in sleep-related quality of life associated with dCBT (adjusted difference at week four, \u22128.76; at week eight, \u221217.6; at week 24, \u221218.72; all P < 0.01). These outcomes were mediated by a large improvement in insomnia (range mediated, 45.5 to 84 percent).<\/p>\n
“These results confirm that dCBT improves both daytime and nighttime aspects of insomnia, strengthening existing recommendations of CBT as the treatment of choice for insomnia,” the authors write.<\/p>\n
